RADIATOR.

Application filed February 23, 1917.

To all whom it may concern:

Be it known that we, FREDERICK LIND- MEIER and J usros Linownnin, citizens of the United States, residing at 735 North Grove avenue, Oak Park, in the county of Cook and State of Illinois, and 819 VVoodbine avenue, ()ak Park, in the county of Cook and ,State; of Illinois, respectively, have invented a certain .new and useful Improvement in Radiators, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

Our invention relates to radiators of the steam or hot water type provided with means arranged to supply to the air in the room in which the radiator is located a certain amount of moisture necessary to the health and'welfare of the persons occupy ing the room.

Before proceeding with the description of the device of our invention and to enable the principal advantages thereof to become fully apparent it may be well to refer in a general way to the devices employed in the past for accomplishing the aforesaid object. It has been the practice to provide a humidifier arranged to contain water and in some instances a screen of cloth or asbestos partly submerged in the water and partly open to contact with the air and to mount the humidifier either behind, at one side, or on top of the radiator. This arrangement is unquestionably unsightly in appearance and is particularly so when the radiator occupies a conspicuous place before a window.

A further and serious objection to these devices is the fact that they .are constructed and arranged in a manner such that they donot utilize the heat of the radiator to the extent necessary for perfect vaporizatlon of the water, and the cause of such failure to operate properly is that the water contained within the humidifier is isolated from the heated parts of the radiator and not in direct contact therewith.

It is one of the objects of our invention to avoid these objections encountered in the past arrangements and to provide a radiator having all the facilities for humidifying the air of the room but which forms a part or parts of the radiator so that so far as the outside appearance of the radiator is concerned it contains no humidifier. A fur- Specification of Letters Patent.

Patented Dec. 11, 191?.

Serial No. 150,391.

ther object of our invention is to construct a device inwhich the water to be vaporized has direct contact with the heat columns of the radiator. In accomplishing this object we provide a water container in which one or more of the heating columns of the radiator form a part of the container walls and with which the Water is in direct contact. These and other objects of the invention will be pointed out in detail hereinafter, reference being made to the accompanying drawings wherein Figure 1 is a front elevational view of a radiator provided with the humidifying arrangement of our invention;

Fig. 2 is a vertical cross sectional view taken along the line 2-2 of Fig. 1 looking in the direction indicated by the arrows;

Fig. 3 is afragmentary horizontal cross sectional view taken along the line 33 of Fig. 2 looking in the direction indicated by the arrows;

Fig. 4: is a view similar to Fig. 3, showing a slightly modified arrangement.

Similar characters of reference refer to similar parts throughout the several views.

In Fig. 1, we have shown a radiator provided with the several heating sections 6-6. Each of these sections contains two vertical columns, as shown at 7-7 in Fig. 2, through which the steam or hot water is arranged to pass. The lower end of each of the sections 6 is provided with the flanges shown at S--8 which are arranged to abut against adjacent flanges provided on adjacent sections 6. The several sections 6 communicate with one another through their lower ends in the usual way and also communicate with the hot water or steam intake pipe shown at 9.

Referring now to Fig. 3, the sections 6 6 and 6 are constructed slightly different than are the remaining sections 6. The section 6 carries a wall 10 extending between the two columns of the section. Similarly, the section 6 carries the wall 11 extending across its upright columns. On the side of the section 6 opposite the wall 10 the section is provided with a pair of flanges 12 and 13 arranged to cooperate with the flanges 14: and 15 provided on the section 6. A suitable gasket 16 is interposed between these flanges so that a water tight joint is secured. A water tight joint is provided between the sections 6 and 6 by similar flanges and gasket as shown. The upright columns of the sections 6 6 and 6 together with the side walls 10 and 11, and the bottom 17 (Fig. 2) form a container arranged to receive the water necessary for humidifying the air. If desired asbestos sheets 18-18 may be placed in the container,',as illustrated in the drawings so that the Water may be vaporized and taken into the air more readily than it otherwise would be. The sections 6*, 6 and 6 are similar in all respects to the remaining sections 6 in so far as the heating functions of the sections are concerned, the sections 6*, 6 and 6 being provided with heating columns, as most clearly shown in Fig. 3.

From the above description and by ref erence to the drawings it will be observed that the humidifying arrangement of our invention does not detract from the appearance of the radiator and, in fact, the humidifying arrangement cannot be seen unless special pains are taken to locate it. It will be observed also that the water within the container is in direct contact with the heating columns of the radiator, and therefore obtains the full benefit of the heat.

In Fig. 4 we have shown a view similar to Fig. 3 of a radiator having more than two heating columns to a section. For this class of radiator we construct those sections which form part of the humidifier so that each contains but two heating columns shown at 26 and 27. The three sections shown in Fig. 4 which form the container walls are provided with flanges which cooperate with one another to form a water tight container. The construction shown in this figure is similar in all respects to that shown in Fig. 3, except that the sections other than those forming part of the humidifier are provided with more than two Vertical heating columns.

Although we have described and illustrated the humidifier as being made up of a certain number of radiator sections we wish it to be understood that as many sections may be utilized for this purpose as are found necessary.

Having thus described our invention what copies of this patent may be obtained for five cents each, by addressing the Commissi we claim as new and desire to secure by Letters Patent of the United States is:

1. A combined radiator and humidifier comprising a plurality of vertically arranged radiator sections, each section including a pair of spaced heating conduits, a pair of vertical flanges, and a base flange forming a part of each of said sections, arranged to cooperate with similar flanges of the adjacent section to form a single humidifier chamber wholly within the radiator, each of said vertical flanges extending from one of said heating conduits and lying in a plane intermediate the inner and outer faces of the conduit to form a holder for a sheet of absorbent material.

2. A combined radiator and humidifier comprising a plurality of vertically arranged radiator sections, each section including a pair of spaced heating conduits, a pair of vertical flanges and a base flange forming a part of each of said sections, arranged to cooperate with similar flanges of the adjacent sections to form a single humidifier chamber wholly within the radiator, each of said vertical flanges extending from one of said heating conduits and lying in a plane intermediate the inner and outer faces of the conduit to form a holder, and a sheet of absorbent material in said holder.

3. A combined radiator and humidifier comprising a plurality of vertically arranged radiator sections, flanges on the sections uniting to form a humidifier chamber wholly within the radiator, and a sheet of absorbent material in the humidifier chamber and extending transversely of the radiator, said sheet being held in place between two adjacent radiator sections.

In witness whereof, we hereunto subscribe our names this 15th day of February, A. D.
